IMPROVEMENT IN MACHINES FOR ASSQR'TING POTATOES.-

The Schedule referred t6 in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that we BENJAMlN D. VANDERVEER, DAVID A. VANDERVEER, and Toms DENISE, of Freehold, in the county of Monmouth and State of New Jersey, have invented a new and useful Improvement in Machines for Assorting Potatoes; and we do hereby declare'that the following is a full and exact description of the same, reference being bad to the accompanying drawing which forms a part of these specifications, and to the letters of reference marked thereon. V I

Our invention consists of a machine having riddles orsieves of a double motion, which separates the potat'o'es into different sizes and deposits them in receptacles or places for each assortment.

Figure 1 represents a front elevation.

Figure 2 is a longitudinal, bi-section.

Figure 3 is a plan showing theriddles or sieves.

Similar letters of reference, where they occur, denote like parts in the drawing.

The machine is put inmot-ion by the turning of the wheel A by means of the crank B. p

The box CO0 is pendent from the bars D D, and derives its swingingand horizontal motion from the bar, E, which is connected with the crank L, shown in fig. 2.

The box 0 G G contains two or more double riddies or sieves, as shown in fig. 2, designated H and H, which move horizontally with the box 0 G O, and derive their upward and downward motion from the action of the rods F 1* F F, on the rails G G G G, constructedin a V-shaped manner.

. I The riddle H allows potatoes small enough to pass through its meshes to drop through, throwing the-f large ones ofi over the end I, the smaller ones falling through on riddle H throwing ofi' those which do not drop through its meshes at K, the smallest ones dropfalling ping-through the meshes of the same and through the bottom of the machine.

By this arrangement potatoes, apples, andother 1 articles required to be assorted can be separated into several different sizes, and with less labor than by any other machine now in use. l Having thus fully described our invention,

What we claim as new, and desire to secure by Letters Patent, is

The box 0 G 0, provided with the double sieves H witnesses. p p
